How the formula works
Both microampere and milliampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microamperes by 0.001 to get milliamperes. To reverse the conversion, multiply a milliampere value by 1000 to get back to microamperes.
Frequently asked questions
What is Microampere (uA)?
A Microampere (uA) equals 1e-06 ampere(s), a scaled unit of electric current used for micro-scale electrical work.
What is Milliampere (mA)?
A Milliampere (mA) equals 1/1,000 ampere(s), a scaled unit of electric current used for milli-scale electrical work.
How do I convert microamperes to milliamperes?
Multiply the microampere value by 0.001 to get the equivalent in milliamperes. For example, 5 uA × 0.001 = 0.005 mA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.001 is an exact, non-rounded value.
Can I convert milliamperes back to microamperes?
Yes. Divide the milliampere value by 0.001, or multiply it by 1000, to get microamperes.
